Ping Pong Games

Ping pong shrinks a sport down to one exchange repeated quickly, which is exactly the shape a browser game wants - nothing to set up and nothing to learn.

Cup Pong Challenge is the throwing version rather than the paddle one, and it's about arc and judgement rather than reaction. Idle Pong takes the format somewhere unexpected by letting it run on its own, turning a reflex game into an incremental one. Money Ping Pong hangs a scoring system off the rallies to give them a point. None of them ask for more than a minute before you've understood everything there is to understand.

There are 3 free games under this tag, all playable in the browser with nothing to install, and none of them ask for more than a minute before you've understood everything.

The quick end is Arcade games, and Incremental Games is where the idle one really belongs.
